Hanna Halaburda and I have written a new book about digital currencies - it will be out at the beginning of 2016. Yes, we do talk about Bitcoin (and its many many competitors) but the book also covers, what we call "platform-based" currencies: currencies introduced and centrally managed by large digital platforms (social networks, retail platforms like Amazon or video game platforms). These have exploded in recent years and we believe that this trend will just accelerate. What might be its implications? This is what we try to answer in the book.
And now we also have a facebook page. Check it out here.
